In Hito Cajon, the frontier between Chile and Bolivia, we got an idea of awaited us for the next 3 days: altiplanic desert, real desert! We entered the Landcruiser (90% of the jeeps here are Landcruisers...) and started. The first day was a candy box, but the feeling of crossing a desert was more real here. You make tens or hundreds of kilometers without seeing any village or gas station. What you see is wildlife, lagoons and desert sized road! In the desert, you don't have one road, you have several since the jeeps may decide to define their own road! Tonight we slept at a refuge in Villa Mar, a small town in the middle of the desert, without phonelines! This actually seems the end of the world...
